Music Theory: Blues Scale

The Blues Scale is a different type of scale which is used to play "over" chord progressions instead of "in" the chord progression. For example, if you have a chord progression of C7, F7 and G7, the C Blues Scale (shown below) can be used to play "over the top" of the progression, regardless of which of the three chords are being played. This scale is used in Blues and Rock music.
